秸秆反应堆技术对设施棚室土壤环境及南瓜光合特性、品质和产量的影响OA

In order to clarify the effects of straw reactor technology on soil environment and photosynthetic quality and yield of pumpkin in greenhouse,in this study,conventional planting(CK)was used as a control to explore the effects of two straw reactor modes of inter-row(HJ)and intra-row(HN)on soil temperature,respiration rate,photosynthetic charac-teristics,agronomic traits and quality and yield of pumpkin during the growth period in early spring and low tempera-ture season.Moreover,it can improve the quality and yield of pumpkin by improving the photosynthetic characteristics and agronomic traits of pumpkin.The average daily soil temperature,soil temperature and soil respiration rate during the whole growth period increased by 1.71-2.31℃,1.94-2.78℃and 12.22%-28.41%,respectively.The photosynthetic characteristics,agronomic traits,quality and yield were increased by 5.71%-29.09%,6.61%-13.00%,6.61%-44.1%and 13.4%-28.3%,respectively,and the effect of straw reactor(HN)was the best.In general,in the early spring and other low temperature seasons,the in-row straw reactor technology(ridge groove length 10 m×width 0.8 m×depth 0.3 m,straw 52 500 kg·hm-2+urea 225 kg·hm-2+activator 1500 kg·hm-2+straw decomposition agent 45 kg·hm-2)should be preferentially adopted in the production of pumpkin in greenhouse to effectively regulate the environment in the greenhouse,promote the healthy growth and material accumulation of plant,and achieve the synergistic improvement of quality and yield.
